"... Abstract—Cold-boot attacks exploit the fact that DRAM contents are not immediately lost when a PC is powered off. Instead the contents decay rather slowly, in particular if the DRAM chips are cooled to low temperatures. This effect opens an attack vector on cryptographic applications that keep decry ..."

"... We give an algorithm that reconstructs an RSA private key given a 27 % fraction of its bits at random. We make new observations about the structure of RSA keys that allow our algorithm to make use of the redundant information typically stored in an RSA private key. We give a rigorous analysis of the ..."

We give an algorithm that reconstructs an RSA private key given a 27 % fraction of its bits at random. We make new observations about the structure of RSA keys that allow our algorithm to make use of the redundant information typically stored in an RSA private key. We give a rigorous analysis of the running time behavior of our algorithm that closely matches the sharp threshold phenomenon observed in our experiments. 1

"... Disk encryption has become an important security measure for a multitude of clients, including governments, corporations, activists, security-conscious professionals, and privacy-conscious individuals. Unfortunately, recent research has discovered an effective side channel attack against any disk mo ..."

mounted by a running machine [23]. This attack, known as the coldbootattack, is effective against any mounted volume using state-of-the-art disk encryption, is relatively simple to perform for an attacker with even rudimentary technical knowledge and training, and is applicable to exactly the scenario

"... Contrary to widespread assumption, dynamic RAM (DRAM), the main memory in most modern computers, retains its contents for several seconds after power is lost, even at room temperature and even if removed from a motherboard. Although DRAM becomes less reliable when it is not refreshed, it is not imme ..."

, it is not immediately erased, and its contents persist sufficiently for malicious (or forensic) acquisition of usable full-system memory images. We show that this phenomenon limits the ability of an operating system to protect cryptographic key material from an attacker with physical access to a machine. It poses a

"... Algebraic side-channel attacks are a type of side-channel analysis which can recover the secret information with a small number of samples (e.g., power traces). However, this type of side-channel analysis is sensitive to mea-surement errors which may make the attacks fail. In this paper, we propos ..."
